What to Check if Central A/C is Not Cooling?

Central air conditioner fan

Why is my central air conditioner not cooling the house under 80 degrees?

If you’ve had problems with your central air conditioning, repairing it now is recommended by most experts. With regard to the aforementioned question, there may not be anything wrong with your central air conditioner, repairs aren’t necessary. As hot as the summer got this year, it is possible that your central air reached its limitations.  But there are common issues that can affect the operation of an air conditioning system: 

  • A clogged, dirty air filter
  • A blocked condenser
  • Leaking refrigerant
  • Leaking air ducts
  • Leaky ducts

While you can have professional central air conditioning repair service for these things, there are two things that central air conditioning repair aren’t the answer:  

  • The central air conditioner unit is too small
  • The central air conditioner has aged out

Instead of having your central air conditioning repaired, these two things will require your purchasing a new system. Can this wait until next spring, or do you need to buy a new system now? Yes, you could wait until next spring, but by buying it now, you’ll be able to purchase at summer close-out pricing and the schedule for installation is probably wide open! 

And there is a third reason: you need your central air conditioning repaired for the heating system. So, the central air conditioning system is needed for the central heat portion of the system to work properly. How does the air conditioning part of the HVAC system affect the heating system?  They have common parts! 

The air conditioning part of your HVAC system chills the refrigerant using the coils, fans, and an exterior unit.  The heater part of the HVAC system uses the coils, fans, and the same ductwork to transport the heated air throughout. 

Why is my central air conditioner not cooling?

As the summer progressed, you may have noticed that the central air conditioning system wasn’t cooling your home, there can be several issues that cause that. On your end, first, check the thermostat was set to “auto” and “cool”.  Then check the air filter and change it or clean it. If all is in proper condition and your home still isn’t cool, it is time to schedule a central air conditioning repair service. 

What is the life expectancy of a central air conditioner?

The average lifespan you can expect from a central air conditioning system is around 15 years, some may last 30 years and others may quit at 8 years.   There are some factors that can affect the average lifespan such as: 

  • The quality of the HVAC system 
  • The quality of the installation
  • The amount of usage 
  • The maintenance and upkeep
  • The insulation level in your attic

How do you clean a clogged condenser coil?

The exterior component of your central air conditioning system is important for the system to properly cool. Here are the basic steps: 

  1. Turn off the power to the air conditioner.
  2. Remove the top and side covers of the condenser unit.
  3. Remove the fan if you can and want to try.
  4. Clean off any debris in and around the unit
  5. Vacuum over the coils to remove any dirt and dust.
  6. Fix any bent fins.
  7. Spray a coil cleaner over the coils.
  8. Using a garden hose, spray water over the coils to complete the cleaning.
  9. Put the air conditioning unit back together.

Go inside the house and make sure the thermostat is in “cool” and “auto” positions and set it 10 degrees lower than the house is currently. After an hour, if it hasn’t cooled the house to the set temperature, call for a professional central air conditioning repair service.

How do you know if the compressor is the problem with your central air conditioning? 

There are some indicators that hint that the compressor in your central air conditioning may be going out. However, these same symptoms can be something else: 

  1. Strange sounds from the outside component.
  2. The air conditioning system overheats.
  3. Warm air blowing from the vent.
  4. Refrigerant level is low.
  5. Moisture leaking from the system.
  6. Energy bills have skyrocketed higher than normal.

In Closing 

While you may be ready for the hot summer to be over and put on the sweaters and heat the hot chocolate, you can’t neglect your central air conditioning system. If it wasn’t in prime working order, any central air conditioning repairs should be done now to ensure the heating system can work properly. Also, by addressing the issues now, it will be ready and waiting to keep your home cool next summer arrives.

Why Would a Gas Furnace Stop Working?

Why Would a Gas Furnace Stop Working?

When winter is approaching, it is important to get any gas furnace repair done now before the rush starts! By Halloween and before Thanksgiving, the temperatures may drop to 32 degrees and below, and nobody wants to wake up in a cold house. 

What are the most common furnace repairs?

Whether you wake up in the middle of the night, early in the morning, or come home after work, you don’t want to walk into a cold house on a winter day. Even here in Orange, California, winter can have a chilly nip to the air! That’s why having your furnace repaired well before the winter months settle in is a good idea. 

Some of the most common gas furnace repairs that HVAC technicians do are:

1. The Air Filter

This would rank number one and is something a homeowner could do themselves! Changing or cleaning the air filter is a must year-round, no matter the weather! When the filter is clogged and dirty, it stops the air from flowing through the vents throughout the house. It isn’t uncommon for a gas furnace to shut down completely when the filter is too clogged. You can avoid a gas furnace repair service call by changing the filter every 30 days.

2. The Thermostat

Technicians often find the gas furnace repair needed is the thermostat. This device communicates to the furnace when to turn on and off and how warm it is to heat the house. A malfunctioning thermostat can keep the heat off and the house cold. Or it may work sporadically, referred to as short cycling, and your home can’t get warm or stay warm. 

3. The Ignition 

The ignition is an essential component as it works the pilot light. This gets its signal from the thermostat, telling it when to cut on or off. Without a pilot light, a gas furnace can’t operate. If you have checked that the pilot light is on and still don’t get any heat, you’ll need to schedule a gas furnace repair service.

4. Wear And Tear

Nothing will last forever, including a gas furnace. A furnace goes through many cycles over the years, taking a toll on the components. When gas furnace repairs cost more than 25% of a new furnace, it is time to replace it. 

5. Poor Maintenance and Upkeep

Just like a car, a gas furnace requires a certain level of maintenance and upkeep. Where your car gets oil changes, tire rotations, and inspections, a gas furnace needs the filter changed or cleaned regularly, the components cleaned, adjusted, and sometimes upgraded. A regular inspection by an HVAC professional that includes cleaning, lubricating, and calibrating the furnace will minimize the need for frequent gas furnace repairs. 

What component fails the most on gas furnaces?

The ignitor and pilot light cause most gas furnace repair calls, but fortunately, depending on the age and brand of the furnace, the parts are typically readily available at a nominal cost. 

What is the most expensive part to fix on a furnace?

Speaking of costs, when it comes to gas furnace repairs, the most expensive part that needs repairing or replacing is one of the following: 

  • The blower motor at an average cost of $2,000 or more
  • The heat exchange at an average cost of $1,500 or more
  • The draft inducer motor at an average cost of $1,500 or more

These are only average guesses for the costs of these components. The actual price can vary based on the age and brand of the gas furnace and the upcharge by the HVAC technician. These prices do not include the labor that somebody will add to your gas furnace repair bill. 

What are the most common reasons a gas furnace may stop working?

The most common problem that gas furnace repair technicians encounter is a dirty or clogged air filter. Other issues they may see include debris, dirt, furniture, rugs, and other objects blocking the furnace’s airflow. This can cause the furnace to overheat and shut down. It would help if you kept a 6-foot distance between furniture, other objects, and the furnace and vents. 

What is the life expectancy of a gas furnace?

Several factors can determine a gas furnace’s lifespan. The brand and installation are vital factors, followed by maintenance and upkeep. Maintenance and upkeep also include getting gas furnace repairs done when needed. The longer you delay, the more damage could happen. The average lifespan is between 15 and 30 years; on rare occasions, some have lasted 40 years. 

For Keeping Warm

Here are five reasons why you should call for a gas furnace repair service: 

  • Your furnace doesn’t turn on
  • Odd sounds are coming from the furnace 
  • The thermostat isn’t responding
  • The furnace is overheating
  • Odd odors are coming from the furnace

How Do I Know if My AC Compressor is Bad?

An air conditioner with a hand using the buttons.

Explore Air Conditioner Solutions

No matter what type of business you operate in an industrial or commercial structure, you need it to be comfortable inside, especially in the Orange, California summers. Employees work better when comfortable, customers spend more time shopping when comfortable, and any materials or products of your business are protected when the interior climate is comfortable. This means having a dependable commercial AC contractor on hand when needed is important.

Are commercial and residential AC systems different? 

No, while they have the same goal, keeping the interior comfortable, a commercial AC system is more complex, mostly because it is larger. A commercial unit requires more power and typically has several zones to treat, spread over more area. As such, commercial AC contractors have additional training than residential AC contractors. Other differences between residential and commercial AC systems include:

  • The placement of the unit. In a home, there is a component inside the house, typically in a closet, and an exterior unit just outside of the home. Most commercial AC systems are installed on the roof for a variety of reasons, such as the noise and the amount of space needed that would take up valuable parking space. 
  • The drainage system of a commercial AC unit for the moisture that accumulates while operating. For a residential system, there is a drain line and drain pan. A commercial AC system, because it is larger, will have multiple drain lines that should be inspected by a commercial AC contractor regularly.
  • The energy use of a commercial system is more than a residential unit. A commercial AC contractor can usually handle the electric wiring, but they may need to bring in a professional electrician if the wiring and connection are complicated. 

What type of maintenance does a commercial HVAC system require? 

No matter what type of HVAC system your commercial or industrial structure has, it will require maintenance to keep it functioning. That maintenance should be on a routine schedule that includes the following tasks, some your own maintenance team can do, and others will need to be done by a commercial AC contractor: 

  • Air Filters: Inspect and Clean

This is a simple step that will have a significant impact on the system’s energy efficiency and indoor air quality. 

  • Thermostat: Calibration

Calibration of the thermostat will keep the interior temperature consistent which eases the energy consumption. 

  • Electrical Components: Inspected

This should be done by a professional commercial AC contractor. They are trained and have the proper tools to inspect and repair if needed the electrical connections, terminals, and wiring.

  • All Moving Parts

Again, this is best when done by a professional commercial AC contractor. They will inspect, clean, and lubricate all moving parts like bearings and motors. Keeping these lubricated will extend the lifespan of the system. 

  • The Coils: Inspect and Clean

Your maintenance team can do this each month, and once a year have a commercial AC contractor inspect the evaporator and condenser coils. They will clean off any accumulated debris and dirt that can hamper the heat exchange and reduce the system’s efficiency.

  • Drainage Lines and Drain Pans

A commercial AC contractor will inspect the drain lines and drain pans, cleaning or replacing them as necessary. 

  • Refrigerant Levels Checked

When the refrigerant levels are low, the compressor can be damaged as the system tries to operate. If the refrigerant is low, this will require a professional commercial AC contractor to add more.

  • Blower Components: Inspect and Calibrated

The blower assembly is what distributes the conditioned air throughout the commercial structure. A professional commercial AC contactor will have the tools needed to thoroughly inspect them and calibrate them to keep them in proper working order.

Additional Steps

With an annual visit by a commercial AC contractor, they will also inspect the air duct system for any blockages or leaks. They will then test the system to ensure it is functioning correctly. 

What are indicators your compressor isn’t working correctly? 

The compressor is a vital part of any commercial AC system, and if you notice any of the following, contact a commercial AC contractor immediately: 

  • Strange sounds: If you hear any clicking, grinding, or rattling sounds coming from the AC system, it often is because the compressor motor is worn out. It can also indicate that there are bat capacitors or relays. Any of these things will need the attention of a commercial AC contractor. 
  • Leaking condenser: If you notice puddles around the condenser, it may be a refrigerant leak, requiring inspection by a commercial AC contractor. 
  • AC isn’t cooling adequately: If the air conditioning isn’t keeping the interior of the structure cool, it can be a few different things. A commercial AC contractor will check the thermostats first throughout the structure, then all the vents. If all seems in good working order, they’ll check the compressor and the refrigerant level next. 
  • Slow to start: If the compressor appears to be struggling to get started, it should be checked by a professional commercial AC contractor. 
  • Circuit breaker tripping: If the circuit breakers keep tripping when the air conditioner starts, this needs to be inspected by a professional commercial AC contractor. 

In Closing 

It is highly recommended to have a commercial AC contractor inspect the system annually. During the inspection, they will inspect the entire system and keep things clean and lubricated as needed. These annual inspections will keep the system in top condition and minimize any emergency service calls while extending the lifespan. If you need a commercial ac contractor in Orange, CA, please get in touch with us at (714) 464-6622.

How Often Should Coolant be Added to AC?

Coolant

Discover the Importance of AC Coolant

When summer arrives here in Orange County, California, it isn’t always a miserable hot summer, but it does get hot enough for the air conditioner.  Because of that, getting the home HVAC system inspected and checked out on an annual schedule is important, especially when it comes to having the AC coolant refilled. 

What type of coolant do HVAC systems need?

HVAC systems require a coolant that is referred to as a refrigerant. In the past, that refrigerant was R-22 called Freon. After much study and research, the contents of R-22 were discovered to be harmful to the environment, and a new refrigerant was introduced, Puron or R410A.  R-22 has slowly been eliminated over the past 10 years or so, and R410A is the only refrigerant readily available.  

Freon and Puron are both registered trade names for these refrigerant products.  Other brand names for the Puron refrigerant are EcoFluor, Forane, or Suva.

What does this refrigerant do in an HVAC system? 

R410A, like R-22, is a low-pressure gas that is superheated. It is injected into an HVAC system by the technician and enters the compressor. The compressor pumps the low-pressured gas towards the condenser, where it is cooled and condensed. The cooled air is distributed throughout the air duct system and out vents in each room.

At this point it becomes a vapor, then becomes a cool liquid with high pressure, creating hot air. That hot air is pushed into the exterior component of an HVAC system and blown out into the atmosphere. 

How often should coolant be added to AC?

The process described above will use that gas refrigerant product over time, lowering the amount of the gas-type product inside the system. This requires an AC coolant refill service on an average of every five years, which has to be done by a licensed, professional HVAC technician.  If an HVAC system requires an AC coolant refill more frequently, it is usually because of a leak. 

Can a homeowner do their AC coolant refill process?

Yes, but it isn’t recommended because the coolant is a gas substance that is under high pressure. Many videos online make an AC coolant refill seem easy, but without the proper tools and the technical knowledge that is needed, it puts the person, and the HVAC system at risk. 

How much does an AC coolant refill service cost?

Because Puron, as the other brands, can only be purchased by certified, licensed professionals, it is expensive and is priced by the pound. On average, an AC coolant refill service call can cost as much as $300 or more. Like any business, professional AC service companies will have various rates. Some may charge by the pound of AC coolant refilled in the system plus a labor fee. Others may have a flat rate, which the final cost will come out about the same. 

Are Freon and Puron the same?

No, even though Freon, the R-22 version, and Puron, the R410A version go through the same process within an HVAC system, they are different. The R410A product is more environmentally friendly. It is a chlorine-free substance that doesn’t deplete the ozone as the R-22 product does.  

With the concerns of the environment around the world, especially in heavily populated areas like Orange County, California, the R-22 is no longer manufactured to help the environment. As such, many homeowners have to replace their existing HVAC system because the R-22 product isn’t as readily available. 

Can R410A be used instead of R-22? 

No, the two refrigerants have different chemical properties with the R410-A being a higher pressured refrigerant. If a technician (or homeowner) were to use the R410-A for an AC coolant refill job, it puts a risk of the entire HVAC system rupturing. This can harm the person performing the AC coolant refill job as well as the home. 

What are some indications an HVAC system needs an AC coolant refill? 

The AC coolant doesn’t have a dipstick like a vehicle’s oil or a gauge like the gasoline. But the following are indications that an HVAC system should be inspected by a professional and could need an AC coolant refill: 

  • The air conditioner constantly runs but isn’t cooling the home.
  • Nothing but warm air is coming through the air vents.
  • The electric bills have significantly increased.
  • There is ice built up on the refrigerant line.
  • You hear a bubbling or hissing sound coming from the refrigerant line.

In Closing 

If you have noticed any of the five indications we just listed with your HVAC system, check the air filter first. If you haven’t changed or cleaned it every 30 days as recommended could be the cause.

If the filter has been changed or cleaned, call a professional HVAC service company. They will inspect and test the HVAC system and if needed, perform an AC coolant refill service. If you need an ac coolant refill in Orange, CA, you can count on us to help! Give us a call at (714) 464-6622 now!

What is Acceptable Indoor Air Quality?

Indoor Air Quality

The state of California is known for strict air pollution laws and requirements for outdoor air quality. They have even established laws to regulate what comes into homes that can affect the indoor air quality

How bad is the outdoor air quality in California? 

It is apparent what affects our outdoor air quality, starting with vehicle emissions, creating up to 40% of the pollution. This is primarily in Los Angeles and the surrounding area there is more than one car per person.  Other contributions to the decline in outdoor air quality here in California are the wildfires, heat waves, and energy sources. 

What are the contributing factors affecting indoor air quality? 

The majority of pollutants that affect indoor air quality come from sources inside our homes and businesses, such as the outdoor climate and the weather conditions, along with human behavior. 

 The weather conditions can cause occupants to keep the windows closed or open. Then when it’s hot, we turn on the air conditioner and when it’s cold, we turn on the heaters and humidifiers. Each of these affects the indoor air quality in our homes, offices, and businesses. 

But there are other contributing factors to harming the indoor air quality: 

  • Combustion Byproducts: Carbon Monoxide, Particulate Matter, Tobacco smoke.
  • Natural Substances: Mildew, Mold, Pet Dander, Radon.
  • Biological Agents: Molds.
  • Asbestos, Lead, and Pesticides.
  • Ozone from Air Cleaners.
  • Various VOCs (volatile organic compounds).

What is considered to be a safe indoor air quality level?

Every day, the EPA (Environmental Protection Agency) analyzes the air pollutants in different locations, breaking them down into 5 groups and how they affect the AQI (Air Quality Index), both indoor air quality and outdoor air quality. 

Ideal indoor air quality as determined by the EPA is under 100. For anything over 100, caution is advised. However, people with existing health issues can have difficulty breathing with an indoor air quality that has an AQI measuring over 51. 

What are the symptoms of poor indoor air quality?

We come home with the feeling that we’re safe and protected. But when it comes to indoor air quality, are we safe and protected? Unfortunately, there are unseen dangers in the air that can make you and your family sick. Some of those dangers include: 

1. Respiratory Issues

If anyone in your home suffers from allergies and other respiratory irritations, this should be an alarming sign that the indoor air quality in your home is not healthy.  Any excessive breathing issues, coughing or sneezing are justifications to have your home’s air quality inspected. 

2. Frequent Headaches

Any person in your home that has frequent headaches can be an indication of poor indoor air quality. There is a wide range of possibilities contributing to this, like VOCs and inadequate air circulation.

3. Fatigue and Insomnia

Poor indoor air quality can make it difficult to get a good, solid night’s sleep. With airborne irritants like dust and pollen, breathing becomes difficult, makes us restless, and falling asleep becomes difficult, only to wake up and have difficulty falling back to sleep. 

4. Excessive Dust 

Yes, all homes will have dust, but if you seem to be constantly wiping that dust off surfaces around your home, you should change the air filter. If that doesn’t help, have your air ducts cleaned and inspected. 

5. Energy Bills Increase

Poor indoor air quality can cause energy bills to increase because the HVAC system is working harder. Have an indoor air quality test performed and this can help determine the exact problem. 

6. Unpleasant Smells

Another indication of poor indoor air quality is persistent unpleasant odors and smells. From a musty smell to a chemical odor, they can be caused by mildew, mold, and other pollutants.

Another indication that your home or business has poor indoor air quality is a high humidity level inside. The humidity should never be more than 50% inside. Condensation on glass surfaces is often caused by poor ventilation, affecting the indoor air quality, and the combination of humidity and condensation can lead to mildew and mold growth, resulting in the air feeling and smelling stale. 

Clearing The Air

So, how can you improve your home or business’s indoor air quality?  Well, first don’t worry that a major investment may not be necessary!  There are three steps you can take that are inexpensive, even free to get better indoor air quality. Those three steps are: 

  • Control the source of the problem: Simply eliminate any individual sources of pollution like sealing or removing any asbestos, make sure gas appliances are connected and functioning properly, and increase the ventilation in the attic. 
  • Have adequate indoor ventilation: Most HVAC systems do not pull in fresh air. When the weather permits, opening doors and windows, and turning on attic fans, the bathroom and kitchen exhaust fans will increase the outdoor ventilation and improve the indoor air quality. 
  • Change or clean air filters: This should be done every 30 days and if there are any occupants with respiratory issues, more frequent can help the indoor air quality. 

Is it an Emergency if My Air Conditioner Isn’t Working?

HVAC units and tool box

Learn About Emergency AC Repair

In Vacaville, California, the summers can get pretty warm, and when your home is humid and warm, you want your air conditioning to work. But when it doesn’t, you need to make sure it constitutes the need for emergency air conditioner repair before you make that phone call. 

What are common signs of an air conditioner in need of emergency repair? 

So, it’s hot in your home, and the air conditioning apparently isn’t working. How do you know if it is a simple problem, like changing the air filter, or if it is an emergency air conditioner repair? The following 6 situations would constitute you have an emergency air conditioner repair: 

  • Unusual noises and sounds: This is the top reason to call for an emergency air conditioner repair service call. Odd noises and sounds are an indication that a component inside the system is damaged, and if the air conditioner keeps running, you may be replacing the entire system. 
  • Warm or hot air: If the airflow coming from the vents is warm, or worse, it’s hot, this is often due to blockage of the airflow. If you change or clean the air filter and making sure the intake isn’t blocked doesn’t help, you need to turn the system off and make an emergency air conditioner repair service call.
  • Ice formation: If you’re seeing water puddling on the floor around the air conditioner system or ice inside the system, specifically on the evaporator coil. Turn the system off for an hour, try it again, and if the ice forms again, make that emergency air conditioner repair service call. 
  • Electrical occurrences: If the circuit breaker trips unexpectedly while the air conditioner is cycling, you need an emergency air conditioner repair service technician to check the electrical components. Unaddressed, it could create a fire hazard.
  • Odors: If you smell electrical or melting plastic, this can indicate something is not working correctly within the system, this is definitely an indication you need an emergency air conditioner repair service call.

How do you troubleshoot an air conditioner before calling for emergency air conditioner repair? 

Well, it depends on the problem you’re having.  If there isn’t any air coming from the vents, check the air filter. Changing or cleaning could be the fix. If the air is warm coming from the vents, check the thermostat is in the COOL and AUTO position. If not, make the adjustment and see if that cools the air. 

If the system is shutting down completely, check the breaker box or circuit breakers and if they are in the off position, flip them back on and try the system again. If these steps don’t fix the problem, make that emergency air conditioner repair service call. In both of these situations, check the outdoor component and make sure nothing is sucked up the unit. This can block airflow and cause it to blow warm air or shut the system off at the breaker. 

HVAC technician working

What should I do if my air conditioner stops working suddenly?

Turn the system off at the thermostat and make that professional emergency air conditioner repair service call.  Never leave the system running when you hear noises or smell something different coming from your system. This can damage the system and even become a fire hazard.

How long does it take for the emergency air conditioner repair technician to arrive? 

This can vary from company to company, and if there is a major heatwave across Vacaville, California. Most emergency air conditioner repair technicians arrive within an hour. Keep in mind that emergency air conditioner repair service calls will cost more when they are after hours, on a holiday, or on the weekend. If you can use fans to keep cool until normal business hours, the service call won’t cost as much. 

In The Heat of the Moment …. 

Once the emergency air conditioner repair technician arrives, they will ask what problem you’re having to give them a general idea. They will check the basics first like the air filter, the air vents, the drip pan and drip tube, and the outdoor component. 

If they don’t find a problem, they will open up the system and inspect the interior guts like belts, fans, etc. They will grease or oil as needed, check the refrigerant level, and other moving parts, making repairs if needed. 

Once they have completed their inspection, they will discuss what they found with you and make suggestions as to what repairs are needed or if the system needs to be replaced. If they are recommending a replacement, you should call for 2 or 3 quotes for a new unit and ask what type of warranty each company offers. While the first emergency air conditioner repair technician may be your knight in shining armor at the moment, you don’t need to make that type of decision in the heat of the moment.

Where Should I Set My Thermostat?

Learn the Importance of HVAC Thermostat Maintenance

California is known for its sun and beaches, Disney, and Hollywood. But do you think about needing air conditioning or heating while there? Probably not, but just like homes all across the country, even homes in Orange, California will need a working thermostat

What is the Thermostat Used For?

A thermostat is a device or an instrument that maintains the temperature within given limits. It turns the air conditioning or heating off when the set temperature is reached. 

There are different types of thermostats, such as the one you use for roasting that Thanksgiving Turkey, or the one in your car that tells you that it’s overheating. 

But in this article, we’re going to focus on the different types of thermostats available for homes.

What are The Different Types of Thermostats for the Home?

There are four types of thermostats used in homes today. They can range in pricing from very inexpensive to very expensive, with each one having a different level of energy efficiency. Those four basic types of thermostats are: 

  • Non-Programmable 

If you’re home more than you’re not, a non-programmable thermostat is a perfect thermostat for your home. The temperature is adjusted manually to your ideal preference. This is the most basic of thermostats.  

  • Programmable 

A programmable thermostat allows you the ability to pre-program the temperature based on when you’re home and at night. These thermostats can be set for each day of the week, and this saves the air conditioning or heating from working when you’re not there, decreasing the wear and tear of the thermostat, reducing your energy bills, and minimizing the need for HVAC  repairs.

  • Wi-Fi 

If you have a computer, smartphone, or tablet, you probably have other devices connected for wireless control. The thermostat in your home can be connected with these types of thermostats so you can access it via a wireless network. This enables the ability to adjust the temperature while you’re away, even overriding the programmed setting if desired. 

  • Smart 

The smart thermostat integrates with other automation tools and equipment in your home, learning your lifestyle habits, then adjusting the temperature accordingly. It recognizes your family’s patterns and stores that information to provide maximum efficiency with your cooling and heating.

A commonly asked question about home thermostats is, “Should I leave the thermostat at a constant temperature?”, and the answer to that may surprise you!

No! By leaving your thermostat at a constant temperature 24/7/365, it is wasting energy and money and wearing the HVAC system out sooner than needed.  

The thermostat should be adjusted down or up according to the weather.  The excerpts at Energy Star recommend setting the thermostat between 70 degrees and 78 degrees, then raising it another 8 degrees when you’re not going to be home. 

How Much Money Will a New Thermostat Save Me? 

This is another commonly asked question because most of us think, “If it’s working, leave it alone.”. This makes sense, but what if it isn’t working at full capacity? 

A new thermostat will save you money, but there are other factors that play into this too, such as:

  • The age of your HVAC system
  • The insulation in your attic
  • The age and condition of the windows
  • The number of people living in the household
  • Where you live and your family’s lifestyle

How Can You Cool or Heat Your Home Without Replacing the Thermostat?

Sometimes, there isn’t any spare money for something like a new thermostat, especially when the current one is working! So, here are a few things you can do to maintain a comfortable level in your home: 

  • Seal the drafty areas like doors and windows in the winter to keep the cold out and the heat in.
  • In the winter, wear layers even inside the house, and in the winter, wear light colors and fewer layers. 
  • Use the ceiling fans! Change the direction they are turning based on the season to help regulate the comfort level in each room.
  • Have a professional HVAC inspection performed annually. 
  • Change the filter every 30 days.
  • Keep the outside component of your HVAC system free of any debris, dirt, and grass that gets sucked up against it. 

Can I Install My Own Thermostat Replacement? 

If you’re a handy DIY homeowner, absolutely! They come with full instructions and there are countless videos online that can walk you through the process. 

Of course, having it done by a professional will ensure that it is done correctly, should have a warranty on the work, and will minimize any chance of something getting shorted out. If you have a regular HVAC technician that does your annual inspections, inquire what they charge to upgrade the current thermostat. 

Keeping It Cozy! 

Your home is an investment and the HVAC system is an investment to that investment. Consider replacing your current thermostat with a newer one as an investment that will provide your ROI with lower utility bills and a comfortable home. 

How often should I have my commercial AC serviced?

Taking Care of Your Building

Sunny California leads to a hot California during the summer. When you’re the one responsible for the comfort inside a commercial building, routine maintenance is important. This is true whether you’re doing your own maintenance or having professional preventive maintenance performed on a regular basis by a commercial AC contractor.

What is commercial HVAC preventive maintenance?

Preventive maintenance is a strategy for being proactive in keeping the HVAC system in good working order. PM (preventive maintenance) by a professional commercial AC contractor will include routine inspections with selective service and needed repairs to the HVAC equipment at scheduled intervals. 

The objective of having a commercial AC contractor perform this preventive maintenance routine is to extend the life expectancy of the HVAC system and prevent disruptions, and unscheduled downtime and reduce maintenance costs overall by correcting defects and issues at the onset. Some specific types of commercial HVAC preventive maintenance strategies are: 

  • Routine Maintenance: Cleaning, inspecting, and servicing is important, and should include changing air filters and other small tasks. This can be done by the building maintenance crew or a professional commercial AC contractor.
  • Proactive Replacements: During professional maintenance by a commercial AC contractor, this will include replacing broken, non-working, and worn building components. 
  • Scheduled Refurbishment: This service is typically done by schools and other learning institutes during scheduled closings. A commercial AC contractor will inspect all components that have defective and deteriorated components, then repair or replace them as needed. 

Preventive maintenance by a commercial AC contractor on a commercial building is akin to that of oil changes on a vehicle. These measures listed above prevent costly repairs over time while extending the life of the system. This saves money for the company and keeps the HVAC system in a healthy and safe operating mode. 

How often should commercial air conditioning units be serviced?

Regular inspections should be performed on commercial, industrial, and other large facilities by the staff maintenance crew on a monthly routine. Professional commercial AC contractors should be inspected and serviced is dependent on the property and any unique considerations. Those considerations can vary based on the occupancy and purpose of the building type, which can include:

  • Apartment Buildings and Condominiums
  • Educational Facilities
  • Healthcare Facilities
  • Historic Buildings
  • Hospitality Real Estate
  • Manufacturing Facilities
  • Office Buildings
  • Retail Facilities

What does AC servicing include?

Preventative maintenance on a commercial or other unique building setups should be serviced by professional commercial AC contractors that include such tasks as:

Twice a year system checkups (fall and spring) should consist of:

  • Cleaning and inspecting the outdoor components
  • Check and regard the refrigerant levels 
  • Inspection and cleaning of blower, belts, evaporator coil, and all indoor cooling system components, replace any as needed 
  • Inspection and cleaning of burner assemblies, ignition systems, and all indoor heating system components
  • Test control systems
  • Inspect and change if needed all air filters in accordance with the manufacturer’s recommendations
  • Check thermostat functioning and reset programming as needed for the season

How often should you inspect your AC unit?

And how do you maintain a commercial air conditioner? There are a few things to keep in mind. The staff maintenance crew should perform the following on a monthly schedule: 

  1. Air Filter Change 
  2. Visually Inspect all areas of the system
  3. Clean Drain Lines and Drain Pans
  4. Clean AC Evaporator 
  5. Clean Condenser Coils

What happens if AC is not serviced?

Neglecting the recommended monthly staff maintenance and annual or bi-annual professional HVAC maintenance by a professional commercial AC contractor can lead to the system becoming inefficient. This causes the energy bills to increase as the system works harder. An HVAC system that must work harder has frequent failures and will need to be replaced sooner than it should. 

How long does a commercial AC last?

If you’re purchasing a new HVAC system for your commercial structure, after the initial sticker shock, you’ll likely want to know, “How long should a commercial air conditioner last?”. In general, the typical lifespan of a properly maintained commercial HVAC system is between ten and fifteen years. With proper monthly maintenance and annual or bi-annual maintenance and inspection by commercial AC contractors, the lifespan can be extended to another 30% or longer.

Keeping Things Cool

A commercial HVAC system isn’t going to be cheap, so, as a commercial structure owner, you’ll want to hold out as long as possible, right? If you’re wondering, “Should I replace my 20-year-old commercial air conditioner?”. A few factors to help you make the decision “now or later” are:

  • The Age: A 20-year-old commercial HVAC system probably looks like a rusty chunk of metal. If it does, there’s your sign! 
  • Wear and Tear: Quality of the equipment and original installation will have a lot to do with this, and so will your diligence in monthly, bi-annual, and annual maintenance. At the 15-year mark, if you’ve had it serviced frequently over the last 5 years by a professional commercial AC contractor, it is time t replace it. 
  • Malfunctioning: When an HVAC unit has minor malfunctions, like dirty filters, squeaking motor, or blown fuses, that isn’t much concern. If it has consistent refrigerant leaking or the fan quits, get the opinion of a professional commercial AC contractor if replacement is the better option. 
  • Outdated: If your commercial system requires R-22 refrigerant still, it is outdated, time to replace the system.

Keeping all this in mind can help you make the right decision, and if you still aren’t sure, a commercial AC contractor can help determine when it’s time to go ahead and update your system.

The Importance of AC Maintenance

Summertime can get hot here in California, so even when the heaters have been blasting for a couple of months, before long the air conditioning is going to be turned up to its max. But when was the last time you did any AC maintenance, or had it professionally serviced?

 Is annual AC maintenance really necessary?

Paying bills, buying groceries, and putting gas in the car are all things that you know are necessary. But is AC maintenance necessary? No, not really. Yes, you read that right – an annual ac maintenance plan is not necessary. 

If your air conditioner is running okay, why waste your money on an AC maintenance appointment? But we can’t promise you nothing will happen going forward into a hot summer, like a blower motor going out, or an air conditioner that will only blow hot air. If you’re lucky, your air conditioning system may continue to run just fine. However, there is no guarantee you’ll be lucky, and having that maintenance can identify and prevent plenty of the problems that may crop up if you aren’t lucky.

What maintenance does an air conditioner need?

Okay, the salesperson that sold the AC system to you recommended an AC maintenance plan. You declined, then the 30-day checkup appointment, the technician recommended an AC maintenance plan. Again, you declined, but you may be wondering, “What does ac maintenance include?”

The two basic maintenance steps are routine filter change and cleaning the condenser and evaporator coil. You’re in charge of the filter changing – every 30 days, the same time you change the smoke alarm batteries. While every HVAC company will have its own process and routines, the following are generally a part of any professional AC maintenance check: 

  • Calibrate the Thermostat
  • Examine the Equipment Condition
  • Blower components
  • Check the Air Handler and Furnace
  • Check Electrical Connections
  • Measure the Airflow
  • Check Safety Controls
  • Check Refrigerant Pressure
  • Check and Clean Drip Pan and Condensation Drain Lines

Once the technician has completed the AC maintenance and inspection, they will review what they found and advise if anything needs to be replaced. They will also discuss with you when to schedule ac maintenance for the next appointment.

What kind of problems does air conditioning maintenance prevent?

Preventative AC maintenance will keep your air conditioner operating at optimum capacity. With the professional AC maintenance of all the components and if any are malfunctioning, the technician replaces the part, lubricates all components required. These steps keep your AC from freezing up and leaving your home amid a hot summer and maximize energy efficiency, which will save you money on your monthly utility bills.

How often should you clean your outside AC unit?

This step of AC maintenance doing it twice a year is sufficient, once at the beginning of summer and again just before fall arrives. All year long you should check around it to make sure there isn’t any grass or other debris sucked up against the unit and always keep the grass trimmed back.         

During the professional AC maintenance check-up and inspection, the technician will check outside components too. This is where they will check the refrigerant pressure, they will open the unit up, and check the electrical components and blower motor.

Should I pay for AC maintenance?

And are AC maintenance plans worth it? Yes, an AC maintenance plan is well worth the cost, within reason. You don’t have to go with the company that installed your unit, although that will probably be the best pricing. The cost of the AC maintenance contract is minimal compared to the cost of a replacement unit! 

How long do AC units typically last?

Today air conditioners can have a lifespan up to 20 years when proper AC maintenance is performed. An older air conditioner will typically last 12 years. There are several factors that will give you the longest lifespan possible from your air condition system, one starting with the quality of the system. A better grade and model, and a quality installation are key in getting a long lifespan. 

Routine homeowner AC maintenance of changing the filter every 30 days has an impact on the lifespan as will annual professional AC maintenance and inspection. By keeping professional appointments, any small issues are found and handled before they become more expensive problems, or worse, replacement!

In Closing 

Here are the four indications that you and the AC maintenance technician will know that it is time to replace your AC unit: 

  • It is older than ten years 
  • Has frequent breaks down requiring returns
  • Energy bills skyrocket
  • AC system is leaking refrigerant

Any of these things individually or a combination of these can be indicators your air conditioning unit is nearing its end of service life. It is important to note that an air condition system that is leaking refrigerant is not normal. If the system is leaking and it isn’t one of the lines, the system will need replacement. 

How can I keep my house cool when the AC is broken?

Dealing With a Broken AC

Way back in time, or so we’ve heard, there wasn’t such a thing as emergency ac repair. Why? Because there wasn’t air conditioning, even here in Orange, California. But today, we are fortunate to have this available to us, and now when it isn’t working, it is an emergency!

What do you do if your house doesn’t have air conditioning? Fortunately, there are other methods for cooling a home like: 

  • Swamp Coolers: Call it old-school, but swamp coolers gave us cooled air for many years before Mr. Carrier invented the air conditioner. They are either mounted on top of the home or installed in a window. There is a sponge insert on 3 sides and you spray those with water. Then the air is pulled in through the soaked sponges and blows into the house. 
  • Attic Fans: Another old-school way of cooling a home by lowering the temperature by keeping a constant circulation of air in the attic The hot air is vented out while the cool air is pulled in. 
  • Geothermal Cooling and Heating: A far cry from the above-mentioned swamp cooler, but geothermal is as old as the earth itself. The underground temps are more consistent than on the surface, usually around 54 degrees, just 10 feet down! A Geothermal system takes advantage of this stable temperature by pulling heated air out in the winter to warm your home. Or it exchanges the warm air indoors for that 54-degree cooler temperature underground. 
  • Heat Pumps: An air-source heat pump will provide an efficient way to cool your home by pumping a refrigerant like that of a refrigerator, through the coils indoors and outdoors. This works like that of a central air unit. 
  • Other Options: To keep your home cool besides central heating and air conditioning include room-to-room air condition solutions like a ductless mini-split system or portable window units.

Should I open the windows if the AC is out?

Yes, should you find yourself waiting for emergency AC repair, here are some helpful suggestions to keeping cool in the meantime: 

1. OPEN THE WINDOWS: While you’re waiting for your emergency AC repair appointment open the windows while the temperatures are cool, usually early morning and late night. Open them in a method where you can get a cross breeze through the house. 

2. COVER THE WINDOWS: Keep blinds and curtains closed in the windows where the sun is shining through the windows directly. If you can hang blankets over the windows to minimize the UV rays coming through. 

3. STAY HYDRATED: Sip cold water or any other cold beverage, avoiding caffeinated drinks and others that can potentially cause dehydration. Sipping is key to making it last longer and not upsetting your stomach. 

4. WEAR BREATHABLE LIGHT COLORS: Dress in fabrics that are lightweight and light colors for the most comfort. Fabrics that are breathable include, cotton, linen, nylon, rayon, and silk. 

5. COOK OUTDOORS: Now is the time to grill outside!  If you must cook indoors, avoid using the oven, or microwave as much as you can. 

6. WATER: Other than for drinking, use water to cool down by taking a cool shower at the hottest time of the day, or mist yourself with cool water and stand in front of a fan. Cold, damp washcloths can keep kids cool as they play (making a game of tossing them back and forth), and of course, water sprinkler time is great while waiting on an emergency AC repair technician. Hook up a dehumidifier can help too.

7. FAN IT AWAY: Set your ceiling fans in a counterclockwise rotation to pull the hot air up to the ceiling. Does putting ice in front of a fan work? Definitely! Place a bowl of frozen ice in front of stand fans to blow the cooled air and ice sprinkles throughout the rooms. 

Is it cheaper to run the fan or the AC?

A fan is a lot less expensive on utility bills than central air conditioning or window units. However, using your ceiling fans WITH the air conditioning is cheaper because the thermostat can be set higher, and the fan will do the cooling. 

What is the best AC temperature to save money?

The EPA (Environmental Protection Agency) advises setting your thermostat at 78 or higher in the summer and 68 in the winter. Because most of us in California and other areas of the country where the summers are blisteringly hot, we want our thermostats much lower. 

For that purpose, a programmable thermostat is ideal. When you’re not home, you can have it set for 78 to 80 degrees during the day (or night) and then have it programmed to cut on to a lower setting within 30 minutes of getting home. Your home will be nice and cool when you come from a long day’s work! 

How many hours should your AC run per day?

A central air conditioning system will cycle every 15 to 20 minutes when in proper working order. At the end of the day, it should not have run more than a total of eight hours with a 24-hour time frame. 

What happens if the AC runs for too long?

The evaporator and coils will freeze up, and the cooled air won’t get blown through the system as intended. Eventually, this will cause the condenser to freeze up and the entire system can burn up. At that point, it is beyond an emergency AC repair, but instead, you’ll find yourself buying a new unit.

An Ever-Present Question: Should I leave the AC on when I’m not home?

We’ve heard yes and no to this question, but in the end, turning it off while you’re gone to work and then back on when you get home will make the system work harder. The harder it works, the more energy it uses, and it will wear the system down faster, needing more frequent emergency AC repair or replacing it before its time.
